- I couldn't agree more. A strong understanding of groups and fields,
- if given early, would probably help students 1) firm up their
- understanding of algebra, 2) firm up their understanding of functions
- (if the right groups were shown). This would help them in calculus
- immensely. Math teaching suffers from a chronalogical problem -- just
- because calculus was invented (discovered if you really want) before
- group theory doesn't mean that it should be learned beforehand.
